Helloworld SR: change template name to instance-profile.

We don't care that it is a template, we care that we are generating the instance profile.
Apache component: Update apr-utils to 1.5.2.
slapconfiguration recipe: cast some parameters from unicode to str.

Those parameters now work if used from buildout and recipes that don't support serialization.
Slapos stack: Use own version of prettytable.
Add slapos-in-partition Software Release.
